• As the step of the color tv ( the second generation ) to the digital tv ( the third generation ) is larger and larger , the research of digital television terrestrial broadcasting ( dttb ) become more and more important in china , we are concentrating on the standard of dttb which is suit for our country after describing and analyzing the technical stipulation and speciality of dttb , this paper compares atsc 8 - vsb with dvb - t cofdm and isdb - t bst - ofdmo the emphasis of this article lies in the technical solution about transferring system , channel coding is important component of dttb , which can resist from the bad circumstances o because of lots of varieties and different performance , channel coding become one of the emphasis of the research work this paper analyzes and researches the theory and performance of the different channel coding particularly , points out an effective theoretic analysis method and computer demo of performance comparison a theoretical method for estimating the performance of concatenated codes is proposed in this paperc this is achieved by combining the performance of single level coding rayleigh fading channel and the character of channel modulation it may be useful to research and development of the future digital television terrestrial broadcasting standard of our country
  信道纠错编码是数字电视地面广播传输系统的重要组成部分，是抵御地面恶劣环境的有效手段。由于信道编码的种类繁多，性能各异，因此是目前研究工作的重点之一。本文详细分析和研究了几种信道纠错编码的原理和性能，并针对外码内码级联纠错结合地面信道瑞利衰落提出了一种有效的理论分析方法和性能的计算机比较演示方案，总结了不同级联方案的性能特点，对于我国目前的数字电视地面广播标准的研究和信道级联纠错方案的确立及其参数选择具有一定的参考价值。
